Visiting Yellowstone National Park in September

In September you’ll find all the park roads, services, and campgrounds are open so it’s one of the best times to visit Yellowstone National Park.

Visitation numbers in September are high so be prepared for crowds during the day. We always recommend entering the park early in the morning, or even later in the afternoon.

Yellowstone Weather in September

The average temperatures in September at Yellowstone are highs in the upper 60s and lows in the upper 30s degrees Fahrenheit.

Be prepared for rain or snow at any time in September. It also doesn’t hurt to pack winter gloves, winter hat, winter coat and fleece jacket – wear layers since the mornings and evenings will be cool.

How Long Should I Plan My Yellowstone Vacation?

We suggest you plan to go for at least 4-5 days to really experience Yellowstone. This way you are not rushed and you can be a little more patient with the crowds of people knowing you have time to see everything. 

Not only that, but 4-5 days gives you time to relax, fish, hike, and really experience Yellowstone for everything it has to offer! Here’s our favorite Yellowstone 4 day itinerary!

Hiking at Yellowstone in September

Before exploring any Yellowstone hiking trails in September, we recommend you check with the rangers at the Visitor Center to get current trail conditions. Also tell someone your hiking destination, route, and estimated time of return.

Stay on trails: taking shortcuts causes trail erosion and is dangerous. In hydrothermal areas, stepping on thin crust may plunge you into boiling water.

Wildlife at Yellowstone in September

Around the second week of September, you’ll begin to hear the high pitched bugle of bull elk signaling the elk rut! The town of Mammoth is a terrific place to watch the male elk exert their dominance.

Bears return to the lower elevations looking for berries and bull bison or elk that perished during the rut. Migratory hawks and eagles begin to travel south and west for the winter.

We’ve put together this resource of the best time to visit yellowstone for wildlife in case you want to see a specific animal in the park.

Remember the parameters to keep you and the animals safe!

  • Never approach animals. The animals in Yellowstone are wild and unpredictable, no matter how calm they appear to be.
  • The safest (and often best) view of wildlife is from inside a car. Always stay at least 100 yards (91 m) away from bears and wolves, and at least 25 yards (23 m) away from all other animals, including bison and elk.
  • Never feed wildlife. Animals that become dependent on human food may become aggressive toward people and have to be killed. Keep all food, garbage, or other smelly items packed away when not in use.
  • Never park in the road or block traffic. Use pullouts to watch wildlife and let other cars pass. Stay with your vehicle if you encounter a wildlife jam.

Yellowstone Photography in September

We recommend you have your camera ready to go because the wildlife you may see as you drive through the park won’t wait for you to find the camera in your car.

In September you’ll also want to photograph the geysers, hot pools, waterfalls and rivers. Here are some tips for taking pictures at Yellowstone.
